3, PVC plastic coated barbed rope protection function is very good

No less than 5 disks should be extracted from each inspection lot for diameter error inspection. 1 point of steel wire should be extracted from each disk to measure steel wire diameter, and the actual diameter of steel wire at this point should be taken as the average value of the two vertical directions. The diameter error of cold-drawn low carbon steel wire should conform to the rules in the table below. The unqualified inspection batches shall be checked one by one, and the qualified batches can be used for engineering.

Compared with the traditional barbed and twisted barbed rope, the raw material cost is relatively high because of the relatively complex process.
